Thanks rooski.  :)


--- Quote from: rooski on September 06, 2016, 07:15 PM ---2.75 is the best ratio for 20" wheels, not sure about 24" bit less I think( 2.3? )

Divide big by small eg 44/16 =2.75  40/15 =2.66 

24" wheel is a different ratio as the bigger wheel is harder to turn.

There is a table on here somewhere.
44t up front is a bit too big for a cruiser, unless your just pootlin' around. I raced cruiser a few years back , started high up front and ended up riding 39/17👍
